Nitra Raises $187M in Financing to Build AI-Native Operating System for Healthcare Practices

Nitra just secured $187M to attack one of healthcare’s most expensive problems. Administrative gravity. The paperwork, payments, procurement, and scheduling layers that quietly swallow time, capital, and sanity inside medical practices. Tim Hwang, CEO, and Jonathan Chen, Founder, President and Co-CEO, are building something designed to cut straight through that operational fog: an AI native operating system for healthcare practices.

The financing stack is built with intention. A $50M Series B paired with a previously unannounced $22M Series A completed in August 2025 delivers $72M in fresh equity. Venture debt adds another $20M from Avenue Capital Group. Then comes the scale lever, a $95M warehouse facility backed by Treville Capital Group and Encina Lender Finance, LLC. The investor roster reads like a global capital syndicate leaning into the thesis. Actions Capital, AppWorks, Comma Capital, Dunamu & Partners, Era Funds, New Enterprise Associates, Pantera Capital, and Sazze Partners joined the round, alongside AAF, Gaingels, Hyphen Capital, K8, Mana Ventures, Necessary Ventures, PIDC Uni President, Purestone Silks, SignalRank, Simu Liu’s Markham Valley Ventures, and Soma Capital. Money like this usually follows momentum. In this case, the momentum is loud.

In 2025, Nitra pushed revenue growth past 740%, climbing from $4M in annualized revenue to more than $33M. Processing volume crossed $1B annually across the platform. In December 2025, the system handled more than $9M in biopharma and medical purchases in a single day. Today the platform supports thousands of physicians operating across more than 700 clinics, including Bay Area Retina Associates, Southern Vitreoretinal Associates (SVA), Elase Medspa, PhyNet Dermatology, Brandywine Urology, and Empower Aesthetics. When doctors trust a platform with purchasing, payments, and workflow operations, that is not casual adoption. That is operational dependency forming in real time.

The platform itself sits at the center of the story. Nitra’s AI native system connects financial automation, procurement, inventory management, and patient operations into one integrated stack. Think Visa powered expense cards, automated bill pay, accounting agents that reconcile financial activity, procurement AI negotiating with suppliers, and voice AI agents scheduling patients while verifying insurance eligibility. Partnerships with McKesson and Medline give practices direct access to tens of thousands of medical products, turning supply chains into something closer to software than logistics.

Step back and the macro picture becomes obvious. U.S. healthcare represents roughly $5.9T in annual spending, and about 25% of that disappears into administrative friction. Nitra is positioning itself directly inside that inefficiency with a platform designed to automate the operational layer of medicine. The roadmap is ambitious. The company expects to surpass 3,000 clinics, exceed $150M in annualized revenue, and process more than $4B annually across the platform while expanding headcount from 50 employees to more than 200 by the end of 2026. Once the operating system inside a clinic changes, the workflows change, the economics change, and eventually the expectations change too. Healthcare rarely moves fast, but when infrastructure shifts, the ripple tends to travel farther than anyone expects.
